The facile tuning of the gate size and chemical functionalization zeolitic imidazolate framework-8 (ZIF-8) were achieved by postsynthetic modification with 3-amino-1,2,4-triazole. resulting amine functionalized ZIF-8 particles enabled CO<sub>2</sub> selective adsorption further modifications.
The efficient removal of radioactive iodine (I2) has drawn worldwide attention because the severe effects radiotoxicity on environment and human health. As a result, porous materials for capture safe storage are required. In this work, nanoscale zeolitic imidazolate framework-8 (ZIF-8) its amino-functionalized ZIF-8 derivatives with 3-amino-1,2,4-triazole (Atz), denoted as ZIF8-A, were prepared via postsynthetic modification, their performance I2 from n-hexane was investigated. abundant...
We prepared polymer/ZIF-7 MMMs with controlled ZIF-7 phases using the polymer-modification-enabled MOF formation (PMMOF).
Abstract Membrane‐based olefin/paraffin separations can be an attractive alternative to the current energy‐intensive cryogenic distillation for their high energy efficiency. This paper reports amine modulator‐induced defect engineering of zeolitic imidazolate framework‐8 (AZIF8) nanoparticles (60 nm) enhanced molecular sieving ability and good compatibility with various polymer matrices. It is revealed that initial suppression nuclei formation during synthesis enables modulators deprotonate...
Energy storage devices (ESD) are getting significant attention regarding their ability to reduce fossil fuel usage. Batteries and electrochemical supercapacitors two well-known ESDs with preferred for high energy discharge potential. The metal oxides (MOs) robust redox characteristics ideal candidates supercapacitors, although capacitance still lacks behind the theoretical values. Here, partial reduced or oxygen-deficient MOs have been identified proven promising reach desired capacitance....
Development of highly active and durable electrocatalysts that can effectively electrocatalyze oxygen reduction reactions (ORR) still remains one important challenge for high-performance electrochemical conversion storage applications such as fuel cells metal-air batteries. Herein, we propose the combination molybdenum-doped PdPt@Pt core-shell octahedra pyrene-functionalized poly(dimethylaminoethyl methacrylate)-b-poly[(ethylene glycol) methyl ether methacrylate] ionic block...
The appropriate treatment of chemical warfare agents (CWAs) is essential because their toxicity and lethality. Metal–organic framework (MOF) catalysts, with the assistance a volatile small molecule buffer, have been reported to be effective for destruction CWAs. However, employing molecular buffers not only contaminates catalysts causes them lose activity but also prevents practical application. In this study, we report novel polymeric buffer that can enhance catalytic ability MOFs without...
We synthesized an ultra-fine Pd nanocatalyst supported by ionic block copolymer doped reduced graphene oxide (Pd-PIBrGO) for ultra-accelerated nanocatalysis.
Abstract Poly(vinylidene fluoride) (PVDF) is common polymer for electrospinning, however, its high hydrophobicity a major drawback, which cause fouling. To introduce hydrophilicity and antibacterial activity, quaternary ammonium-functionalized amphiphilic diblock copolymers were synthesized blended with PVDF/graphene oxide (GO) solution, then, electrospun coated hydrophilic polymer, poly(vinyl alcohol) (PVA). The block copolymer, consisting of hydrophobic poly(methyl methacrylate)...
Continuous and safe decomposition of chemical warfare agents (CWAs) is a critical requirement to protect both soldiers citizens eliminate the stockpiles after cold war. The Zr-based metal–organic framework (Zr-MOF) has been known as most effective catalyst for decomposing CWAs, especially fatal nerve agents, however, its low processability due powder form limits expansion actual military applications. To this end, composite membrane catalysts (CMCs) comprising Zr-MOF (UiO-66 catalyst) nylon...
